Abstract: This seminar seeks to provide context on global change biology by examining species that are on the opposite end of the biodiversity spectrum. Through space and time species can become (a) increasingly abundant, or (b) dramatically diminished. On one hand, species that become increasingly abundant can generate ‘bad press’, such as controversies surrounding ‘noxious’ / ‘invasive species. On the other hand, species that are dramatically diminished are classified as ‘near endangered’('good press'), while becoming posterchildren for biodiversity. In this featured presentation, (1) we report microevolutionary changes in non-indigenous - ‘noxious’ chicory (Cichorium intybus). Also, (2) a closer look is taken at the ‘invasive’ Colorado potato beetle (Leptinotarsa decemlineata), while using microbes as agents of integrated pest management (IPM). Finally, (3) population decline in ‘near endangered’ monarch butterflies (Danaus plexippus) are assessed by examining negative CO2 induced effects and environmental contaminants (i.e., PAH). In conclusion, gaining insight into environmental change and its effect on communities may be key to understanding our changing world.
